This site is my way to share my views and general business and IT information with you about Microsoft, IT solutions for ISVs, technologists and businesses, large and small. I specialise in Windows Intune and SBS 2008.

First off I have some bad news for you - this pack no longer exists (although if you search the web hard enough you might find someone with a legitimate one to sell). However, this pack would have taken you to Windows 2000 - not exactly the best destination, so what are your options?

Migrate to SBS 2003 and get the Transition Pack for SBS 2003

Ditch SBS and just buy Windows Server 2003 and migrate the information by hand

If the number of users is still going to be below the 75 CAL limit and it was the 50 CAL limit of SBS 2000 that was the problem, then simply move to SBS.
